Can you name these celebrity guest stars on 'CHiPs'?

If you were famous in the late 1970s, you probably met Ponch and Jon.

CHiPs was riddled with celebrity guest stars. Ponch and Jon were patrolling Southern California, after all.

If you were famous during the show's run, between 1977 and 1983, odds are you made an appearance. The two-part "Roller Disco" and "The Great 5K Star Race and Boulder Wrap Party" episodes alone served up dozens of Seventies stars.

Spotting the famous faces is part of the fun when watching CHiPs. Let's see how well you remember these cameos.
